Yes,I followed the example in the API documentation.I'm a beginner. I'm not sure in the steps below.

Calculating the SignatureCalculating the value to include in the request is a simple procedure.1.Calculate an RFC 2104-compliant HMAC-SHA1 hash, using the string (see 4.3.2) and the user's password as the key.2.Convert the resulting value to base64.3.The result is the signature you include in the request.

it looks ok to me. Do you get the right value when you use the date and password defined in the API ocs as an example? (search for "The following table shows a string, a fake Secret Access Key, and what the resulting base64 encoded signature would be.")
